image 10 latent prints copy store on curved surfaces: Bottleneck glass with the method of magnetic powder (a) glue Tex-Lift (b) and transparent silicone. (c)
.Discussion on the research of image 6 indicate an average percentage of the number of points the special significance of the pattern of the fingers and latent. Check the store on rough surface and curved surface with the method of A magnetic powder, how B glue Tex-Lift and how C silicone.The special significance of latent prints more than other methods. Because the properties of transparent silicone, that the compounds semi liquid. Which can flow to the roughness of the surface is uneven, can be copied to keep out.Tex-Lift to use transparent tape helps to peel off from the surface of the object from the works of Mill Morris reported that made transparent silicone can be used. Check the trace of latent fingerprints on the curved surface, surface in the horizontal and vertical surfaces (Morris 2005).In this research, applied transparency drilled a hole to fit a latent fingerprints and put up into a top-notch latent fingerprints. Want to keep. Before the coated with transparent silicone.In each sample rate, not too thick for easy verification comparison, or can use the Spreader tip company Lynn. Peavey limited. Connect to the end of the tube of the infusion sets of mixing automate. The silicone sheet, smooth แบนสวยงาม1 inches (Frost 2005:35) using glue Tex-Lift in lifting latent fingerprints. The quality of a latent fingerprints on the surface is uneven. But there are some problems on curved surfaces, a knob and a bottleneck glass.In addition to the latent fingerprints on it. Curved surface also cannot use the transparent tape help to peel the adhesive sheet coated on a latent fingerprints. Because the tape, can't bend along the surface of the object.Horizontal surface, which can use the transparent tape help to keep a copy of latent fingerprints. So in storage. The latent fingerprints on the smooth curved surface is adhesive coated onto a top-notch latent fingerprints thicker than on the ground. The rough skinExcess glue and some will drip down. Making it difficult to copy store has Roy latent fingerprints was complete, which depends on the skill. Of the samples were obtained. From the image and 9 10.Will that prints concealed, copy stored in each method to strokes clear is similar, although image 9 (a) and 10 (a) is a channel. Leisure arise from the use of transparent tape. The strokes missing discrete, but is only a small partLatent prints stamped down on the curve of the objects in this research is intended to เห็นลายเส้น. Jane and curved surfaces, such as A glass bottle and metal general surface smooth, no porosity. So the prints.There is only a small part, only missing a. But in the scene may be found. Latent prints only small parts If collected Roy latent fingerprints might not be the latent prints.Therefore, one option is to use the new technique in this collection. The latent fingerprints to powerful
.Suggestions 1. Chemicals used in this research to be purchased from abroad. It should contain chemicals that looks like a glue or transparent silicone. With domestic sales production was compared in order to reduce the cost 2.In lifting latent fingerprints with a new technique to training practice to achieve the Cham Na specialize in lifting latent fingerprints. And should have intention to a latent fingerprints becauseScience 3.Can be used as a guide in the research of surface type. Luggage a latent fingerprints was difficult, such as human skin, blood 4 prints.Can be used as a guide in choosing how to keep the latent fingerprints to veer like objects. Each witness types. To obtain a latent fingerprints with good quality
